Hi, I'm having trouble importing into my application using Core Data. I have an NSAtomicStore based storage system. I can open and save my own files, but when someone wants to import from another format, I want to load the file and set the file name to nil so that I can save it as my own file type.
I have overridden -readFromURL:ofType:error:, and if it's one of the types I want to import, I spawn a separate process which converts it to my file type and then I call super with the newly created file that I want to read, and then set the file url to nil and set the file type to my file type, so that I end up with an untitled file which I should be able to save. The problem is that when I save, it starts off with the standard operation of creating the temporary file in the folder "(A Document Being Saved By...)", but then it goes wrong - instead of updating and saving back to that temporary file, it saves the file at the location it was originally loaded from. This leads me to the conclusion that something in the persistent store or managed object system has kept track of where it was originally stored, and is confused by the fact that I have set the url and file type. Does anyone know how I should be doing this so that I don't have this problem? I hope this explanation is clear enough - let me know if you need more information...
